A stroke is caused by the interruption of the blood supply to the brain, usually because a blood vessel bursts or is blocked by a clot. This cuts off the supply of oxygen and nutrients, causing damage to the brain tissue.
The effects of a stroke depend on which part of the brain is injured and how severely it is affected. A very severe stroke can cause sudden death.
